描述

TVD1.3-15-03

结构化文本（ST）是一种高级的文本语言，可以用来描述功能，功能块和程序的行为，还可以在顺序功能流程图中描述步、动作和转变的行为。结构化文本语言表面上与PASCAL语言很相似，但它是一个专门为工业控制应用开发的编程语言，具有很强的编程能力用于对变量赋值、回调功能和功能块、创建表达式、编写条件语句和迭代程序等。结构化文本非常适合应用在有复杂的算术计算的应用中。结构化文本程序格式自由，可以在关键词与标识符之间任何地方插入制表符、换行字符和注释。对于熟悉计算机高级语言开发的人员来说，结构化语言更是易学易用。此外，结构化文本语言还易读易理解，特别是用有实际意义的标识符、批注来注释时，更是这样。

主营：本特利，英维思，伍德沃德，福克斯波罗、西屋、瑞恩、施耐德莫迪康、ABB、AB、西门子、摩托罗拉、GE发那科、安川、博世力士乐，ACSO，力士乐等各大品牌的DCS系统配件，机器人系统配件，大型伺服系统备件。

先介绍几点经验。
1、先通读一遍“系统手册”（不管能不能看懂，先了解个大概，以便学习编程时查找）；
2、由位控逻辑入手，逐渐增加定时、计数等条件，把或、与、非关系理顺；
3、进而练习整数运算、实数运算、类型转换；
4、量程转换、PID调节回路的建立及P、I、D参数的理解（最好是有个物理回路验证，比如变频器+电机+测速传感器）；
5、循环、顺序、跳转等程序控制（尽量避免跳转，非跳不可时也是跳的越近越好）；
6、中断、通讯、位置控制....

本人以ABB工业机器人配件DSQC系列和Motorola MVME系列，GE 卡件 模块 驱动器系列为主攻。各位电工朋友可根据自己的条件选择适合自己的PLC品牌，由于PLC的基本框架大同小异，学会一种至于其它的学习起来也就简单了。
